I have been very happy with the 300W quiet spindle but now that I have gained a little experience and put a lot of hours on the machine, I can see that it is starting to show some signs of wear in the form of runout caused by the lower bearing wearing out.
While learning to use the X-Carve I have acquired a number of bits and ER11 Collets. My bits are 1/4", 1/8", 4mm and 6mm.
So ideally I would like to find a new (more powerful) spindle that can also use the ER11 collets. Is there such an animal?
I know I can just bite the bullet and purchase the Dewalt 611, purchase three new collets and call it a day. But I am a bit suspect of changing bits on the 611 with the push lock for the spindle shaft. It seems to me that I will be more likely to move the spindle location when changing bits on the 611.
With the two wrenches on the ER11 the forces are balanced and I can change the bit without moving anything.
Or maybe not that I am less likely to abuse the spindle (the first 10 hours of use use were hard on the machine and spindle with a few scary moments of crazy deep cuts and wasteboard drilling). I should just get another 300W quiet spindle and start fresh.
